• Manufacturer Part Number: AU2903
• Description: Low Power Dual Voltage Comparator
• Manufacturer: NXP Semiconductors

1. Positive excursions of input voltage may exceed the power supply level by 17 V. As long as the other voltage remains within the
2. At output switch point, V
3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of
4. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of
5. The response time specified is for a 100 mV input step with a 5 mV overdrive.
6. For input signals that exceed V

Low power dual voltage comparator
common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than –0.3 V
below the magnitude of the negative power supply, if used).
V+ –1.5 V
the common-mode voltage range is V+ –1.5 V, but either or both inputs can go to 30 V
the output so no loading change exists on the reference or input lines.
and a limiting resistor should be used on all inputs that might exceed the positive supply.
